Description

[Detailed description of the invention] The present invention relates to an improvement of a wire ring convergence device, and in particular, provides a wire ring convergence device that prepares wire rings and obtains wire coils with good packing appearance, and at the same time prevents wire coil flaws. This is what I am trying to do.

A wire ring convergence device is a device that serves to condense wire rings that have been continuously deployed in a non-concentric manner on a cooling conveyor into a single wire coil.
The schematic configuration is as shown in FIG. The focusing state by this device is performed as follows.

FIG. 1 is a side sectional view schematically showing a focusing situation that is problematic in a conventional focusing device. In the figure, a wire ring 1 is conveyed while being cooled by a cooling conveyor 2, is conveyed while being sandwiched between chain conveyors 3 and 3', is discharged almost directly above the center of a focusing tube 4, and falls inside the focusing tube 4. As a result, a weighted coil is formed using a carrier 6 provided at the lower center of the focusing tube 4 as a winding core.

When one wire rod has been bundled, the ring separation device 5, 5' is projected into the collection device by the air cylinder 7, 7', and the subsequent wire rod rings fall onto this separation device 5, 5', temporarily The wire rods that have been stored and focused on the carrier 6 during that time are taken away together with the carrier, and an empty carrier is prepared at the same position, where the separation devices 5, 5' simultaneously separate the focusing cylinder 4.
The rings on the separating devices 5, 5' fall into the carrier, and the subsequent rings also fall into the carrier one after another.

The chain conveyors 3 and 3' are for dropping the wire ring 1 horizontally into the center of the focusing tube, but as shown in Figure 1, the tip x of the ring 1 that leaves the chain conveyor first falls down due to the influence of gravity. , it is inevitable that the ring 1 will fall diagonally.

The degree of this diagonal fall varies depending on the wire dimensions, the weight of the ring on the cooling conveyor, the chain conveyor speed, etc., but if it falls too diagonally, the link 1 will not enter the carrier 6 and will come off. Arrow Y in FIG. 1 indicates a case where the ring 1 is too oblique and does not enter the carrier 6 but comes off.

Therefore, when the ring 1 falls onto the carrier 6, that is, when it falls downward from the separating device 5, 5', from the tip of the ring 1, some rings are centered against the carrier 6. Since the wire rod 8 falls in the shifted state Z, the bundled wire coil 8 has a poor packaging appearance, as shown in an enlarged view in FIG. If the bundling process is carried out in this state, the ring 1
This can cause various problems, such as slippage and surface flaws, or damage to the binding material during cargo handling, making it impossible to handle the cargo. Furthermore, since the wire rod coil 8 is used as a raw material to manufacture secondary processed products, the quality of the wire rod coil packaging and coil flaws are treated as important control items in terms of quality control as they affect the product value. .

The purpose of the present invention is to solve such problems and provide a wire coil convergence device that can improve the appearance of wire coil packaging.As shown in Figure 3, the present invention is characterized by the ability to separate coils of wire rings. In the focusing device having the device, the coil plate is rotatably supported via a shaft 17 provided on the coil plate, which is located between a plurality of door pins 12 attached to the coil plate and located downward facing the direction of movement of the wire ring. A drive device is connected to one end of the member 15 via a rod 16, and a load shape correction rod 13 having a covering material 18 is provided at the other end of the member 15 so as to be movable back and forth. 1, 2, 3, 3' in the figure,
Since the respective symbols 4, 5', and 7' are the same as in FIG. 1, their explanation will be omitted.

Now, the means to make the load straightening rod 13 move forward and backward (in the coil radial direction) is to attach an air cylinder 14 (a hydraulic cylinder may be used) to the outside of the coil plate 11 as shown in FIGS. 3 and 4. The cylinder rod 16 is connected to one end of a member 15 which is rotatably supported on the coil plate 11 via a shaft 17 at an intermediate position, and the load shape correction rod 13 is erected at the other end of the member 15. and configure. It is preferable to provide a pair of such load correction mechanisms facing each other as shown in FIG.

Further, the load straightening rod 13 is provided with a covering material 18 made of heat-resistant resin, heat-resistant rubber, etc. so as not to cause scratches or the like when pressed into contact with the wire ring 1.

Such a focusing device 10 operates as follows.

FIG. 3 shows a state in which the carrier 6 is not attached and the coil plate 11 to which the door pin 12 is attached is open and on standby. When focusing, the first
As shown in the figure, the carrier 6 is automatically installed so as to be positioned inside the coil plate 11, that is, below the focusing tube 4. At this time, the coil plate 11 closes and the door pin 12 serves to focus the falling wire ring 1 onto the carrier 6.

When or after the wire ring 1 reaches the carrier 6, the air cylinder 14 is automatically operated to move the straightening rod 13 having the covering material 18 to the door pin 1.
2, the center of the wire coil 8 shown in FIG. 2 is forcibly pushed in, and as shown in FIG. At this time, since the straightening rod 13 is provided with the covering material 18, there is almost no possibility that flaws will be induced in the wire ring 1 or the wire coils 8, 8'.

After correcting the cargo shape, the air cylinder 14 is automatically operated to move the cargo shape correction rod 13 to the door pin 12.
Move backward from between the two and wait. At the same time, the coil plate 11 is also automatically operated to open and stand by as shown in FIG.

Since the present invention is constructed and operates as described above, it has the practical effect of solving the conventional problems shown in FIG. 2 and producing a large quantity of wire rod coils with good packaging. It also prevents damage to the binding material and eliminates troubles during cargo handling. Furthermore, all of the above-mentioned problems can be solved, such as coil flaws.
